The present invention relates to terpene resin, particularly to a method for preparing beta-pinene polymers with high molecular weight. The method adopts catalysts comprising alpha-diimine nickel complexes (main catalysts) and methyl aluminoxane (auxiliary catalysts) for catalyzing beta-pinene monomers so that the beta-pinene monomers are polymerized. The method provided by the present invention can prepare beta-pinene polymers with high molecular weight at high polymerization temperature (40 DEGC) and at low catalyst concentration (6.92*10<-4> to 6.92*10<-5>mol/L). The number average molecular weight of the obtained beta-pinene polymers is larger than 4000, and can reach 7450 furthest.
Description
Technical field
The present invention relates to terpine resin, specifically, relate to a kind of method for preparing the high molecular beta-pinene polymer.
Background technology
Natural terpenes monomer beta-pinene
Be terebinthine main component, its polymerisate is that terpine resin has good tackifying, anti-aging and thermostability, is widely used in industries such as pressure sensitive adhesive, hot melt adhesive and elastomer-filled dose.Simultaneously because the characteristic of its nontoxic odorless, resistance to chemical attack also can be used for food and medical industry.
Beta-pinene is sour as AlCl at Lewis
3Deng, realized suitability for industrialized production by the synthetic terpine resin of cationoid polymerisation.But there is following several respects shortcoming in the beta-pinene cationoid polymerisation under the Lewis acid catalysis: in order to obtain to have the polymkeric substance of practical use molecular weight size, polymerization must be carried out under lower temperature (<0 ℃) (1); (2) for making the beta-pinene conversion of monomer complete, Lewis catalyst consumption big (be generally monomer consumption 1~4%) and cause the last handling process complexity of polyreaction; (3) even under lower temperature, the also not high (M of molecular weight of the poly-beta-pinene of polymerization gained
nIn 1000~4000 scopes), this has limited the application in the material (as elevated temperature heat melten gel etc.) that thermotolerance is had relatively high expectations as tackifier or weighting agent of beta-pinene resin.
Therefore, can be under higher polymerization temperature and lower catalyst concn synthetic more high molecular beta-pinene resin, will have important practical application meaning.
